Heat can set stains permanently. Once you toss the item into the dryer, the stain is set for good. If the stain remains after the first wash, pre-treat and wash again before drying to try and remove the stain. 5.
However, most stains will become permanent if left untreated too long. When first coming into contact with fabric, most stains will initially remain on the surface and can be removed relatively easily. Over time, stains absorb into the fabric and permeate the fibres. They begin to react with the fabric's dye.
Hot water will set some stains, particularly protein based stains. Use cold or warm water on these before washing in hot water. Always test to be sure that a stain removal product will not damage fabric by applying to a small part of the fabric that is not easily seen.
If a stain has "set", it has become chemically bonded to the material that it has stained and cannot be removed without damaging the material itself. It is therefore important to avoid setting stains that one wants to remove.
Once you have washed the item, check it to ensure the stain is completely removed, since drying can actually set the stain. If the stain is still there, you may need to use this same method again, or you may want to move on to another solution for the removal of set stains.
Depending on the type of stain you are using, most stains are dry and cured within 24 hours to 48 hours. After that time, it's safe for additional coats or to apply polyurethane or the sealer of your choice.
Unfortunately, some stains are permanent, and not even the best cleaning methods can remove them. If you notice a stain on your clothes, do not try to remove it yourself. Washing a stain or attempting to remove it with a home remedy can actually ingrain it further into the fabric and make it permanent.
Stains on clothing and linens can be annoyingly stubborn, but they don't have to remain a permanent feature on your garment. Even notoriously difficult stains like red wine or ink can be removed from most fabrics. For all fabric stains, it's important to act fast and treat the spot as soon as possible.
Water stains can be removed relatively easily from washable clothing.

Air-drying won't lock in stains
Pro tip: If you air-dry a stained item, you can continue to treat the stain and wash the item until it's removed. Oil-based stains aren't easily removed using water, so it might be smart to dry clean to remove it.
If a glass of your favorite wine, dry or sweet, spills on the tablecloth – act quick. The natural absorbing properties of the fibers cause them to “take over” moisture and dye, which is then distributed over the fibers and dries, thereby permanently discoloring the linen material.
Oil stains can be permanent, but that is not always the case if they are treated and cleaned quickly after they happen. Blotting and removing excess oil and treating the stain as quickly as possible will increase the possibility of successfully removing it.
If you feel like it's your only option, though, start with diluted oxygen bleach and move on to chlorine bleach if necessary. Really old, stubborn stains sometimes respond best to liquid glycerin. Rub it in, let it soak and then launder again.
“A paste of vinegar and baking soda can remove even the toughest stains,” she says. There's a misconception that vinegar will remove color from clothes but in fact, it's gentle enough to use on most fabrics, vinegar can actually restore and brighten color in fabric and can also prevent fading.
Old Stains There is often the effect of time upon a stain: the older the stain, the harder it is to remove. Drycleaners who are trained in stain removal prefer to work on fresh stains which have not had time to "set" or react with the fabric, dyes, finish, or atmosphere.
Wood stain is intended to be wiped off immediately after application. If the wood stain remains on the wood, liquid solvents in the stain will evaporate, leaving sticky pigments behind that will never fully dry. To remove tacky wood stain, firmly scrub the piece with mineral spirits.
If the stain stays on too long, the wood will absorb too much stain. As a result, you may have a darker shade than you anticipated—or uneven coloring. Likewise, the stain can start to peel and flake off. The wood may also discolor or become blotchy.
In general, hot water is more effective for removing oily or greasy stains as it helps to dissolve and lift the oils. However, hot water can also set protein-based stains like blood or sweat, making them harder to remove.
Paint tends to last a little longer than most stains, coming in at around 8-12 years before you will likely have to repaint. Stain, on the other hand, typically has to be refinished every 5-10 years.
